Lostsunrise [7]

Answer:

  no

Step-by-step explanation:

The prices are inconsistent, so there is no unique price that can be set for either an apple or an orange that will give the total prices indicated.

__

The first relation can be written as ...

  $10 = 4A +4O

  $10 = 4(A +O) . . . . factor out 4

  $2.50 = A +O . . . . divide by 4

The second relation can be written as ...

  $12 = 6A +6O

  $12 = 6(A +O) . . . . factor out 6

  $2 = A +O . . . . . . . divide by 6

These two relations give different prices for 1 apple and 1 orange. There is no price that can be set for either fruit that will give this result.

No unique prices can be assigned.

The veloctiy of sound in air is given by the equation v=20 times the square root of 273+t where v is the velocity in meters per
Nikitich [7]
So we just need to plug in our values and solve
v = 20 \sqrt{273 + t}
we are given v is 369 so we have
369 = 20 \sqrt{273 + x}
now we solve for x.
divide both sides by 20
square both sides
subtract 273 from both sides
369 = 20 \sqrt{273 + x}  \\ 18.45 =  \sqrt{273 + x}  \\ 340.40 = 273 + x \\ x = 67.4
so a temp of about 67 degrees C
